The City of Petaluma requested a temporary change to the operation of the “D” Street Drawbridge. The “D” Street Drawbridge's navigation span provides 7 feet of vertical clearance, at Mean High Water, in the closed-to-navigation position. The drawspan opens on signal if at least 4 hours notice is given for openings from 6 a.m. to 6 p.m., and if at least 24-hours notice is given for openings from 6 p.m. to 6 a.m. Start Printed Page 50723

The drawspan will be secured in the closed-to-navigation position, from 6 a.m. on September 3, 2008 through 7 p.m. on November 14, 2008, to allow the City of Petaluma to conduct needed maintenance, which includes; trunion pin replacement, deck resurfacing, and painting of the entire structure. To facilitate the maintenance, the contractor will install scaffolding beneath the bridge deck, reducing the vertical clearance provided for by the bridge in the closed-to-navigation position, by 5 feet.

From September through November, 2005-2007, the drawspan averaged 294 openings for vessels. This temporary deviation has been coordinated with waterway users. There will be no impact to commercial waterway users, no dredging is scheduled during this deviation period, and the City of Petaluma Visitors Bureau has been informing recreational waterway users of the maintenance. No objections to the proposed temporary deviation were raised.

Vessels that can transit the bridge, while in the closed-to-navigation position, may continue to do so at any time.

In the event of an emergency the drawspan can be opened with 24 days advance notice.

In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.
